Thanks to Albert Omoss for this:

#include <octane-oslintrin.h>
shader Texture(
color col1 = color(0.5, 0.5, 0.5),
output color c = 0)
{
color col2 = _evaluateDelayed(col1, u, v);

c = color(col2[0], 1.0 - col2[1], col2[2]);
}

works perfectly.

Does anyone have any OSL coding experience? I'd happily pay for an OSL shader that allows me to invert the Green channel of a texture. Though this functionality should be built into Octane. Seeing how everyone else has this function (including Physical).

I have a bunch of OpenGL based normal maps that I need to flip the green (Y) channel on in Octane. Anyone know a trick or perhaps has an OSL shader that does this?

Thanks in advance!

I apologize if this has been covered in a previous post, but I'd like to learn more about the ai denoising settings. Is there any documentation covering all of its settings in Cinema 4D? Thanks!

I really hope someone can shed light on this. I'm trying to create physically plausible materials in Octane and not knowing how spec energy works with mix materials is making that difficult.

I have a question about something I have not been able to figure out about Octane Mix materials. When I'm mixing SSS medium shaders that have no spec and glossy shaders that do have specular, how do I maintain the specular energy of my glossy material?

By mixing the two materials, the specular is ...

Will the latest Octane 3 installer work in R18?

Thank You,

Cool, thanks so much!

Cool approach Calus, I'll try that tonight! Thanks!

Here are a couple of ideas for the Random Color node:

- Inputs on the color correction node for all settings to allow the randomization of everything, not just brightness
- A switch node where the random color can be turned into an integer that would pull textures from a switch node (bunch of ...
